STAIR-TBEAD NOSING.

Original No. 1,611,211, dated December 21, 1926, Serial No. 57,293, filed September 19, 1325. Application for reissue filed December 14, 1928: Serial No. 32s,115.

This invention relates to nosing members for stair treads and consistsof a nosing construction of improved form designed to have important advantages over nosing members as heretofore made and is, moreover, of sinu ple form adapted to facilitate installation.

The improved nosing or edging member of the present invention is of the type pa-rticularly adaptedfor the protection of the edge of coverings, such as linoleum, compo-- sition, cork tile, rubber tile, and of similar materials when used on stairs, landings, floors, etc. where the edge would be subjected to destructive wear. It is, moreover, of the simple and well known form comprising, as an integrality, a substantially vertical edglng or facing flange, preferably of curvilinear cross section having a horizontal securing flange projecting rearwarclly therefrom to bear upon the floor or tread surface and provide means for securing the edging or nosing thereto. As heretofore made,the horizontal securing flanges of this desirable type of nosing have been of uniform thickness and, in consequence, it has been necessary to build up to covering rearward of the nosing or to cut away or rabbct the forward marginal edge surface of the stair tread or to similarly rabbet the undersurface of the floor covering so as to avoid the excessive wear incidental to the shoulder or high edge at the rear end of the securing flange. and to eliminate the danger incident to the shoulder thus formed. In accordance with the present invention, the necessity for rabbeting the stair tread or floor covering is eliminated by'a simple and improved form of securing flange which, in its cross section, has its under-surface normally in a horizontal plane and its upper surface inclined progressively to a rear edge that is relatively thin or of minute thickness whereby there is no appreciable shoulder produced. As a result, the improved nosing may be inexpensively installed by merely placing same upon the surface of the stair tread memher without cutting and the covering may be laid thereon wlthout danger of excessive wear. 7

The described and other features and advantages ofthe present improvements will be more fully understood by reference) to the accompanying drawings wherein- Fig. 1 is a perspective view illustrating the improved nosing of the present invention as installed.

Fig. 2 is a vertical cross-sectional View of the nosing member.

In the improvedembodiment of my invention, applied to a stair treadfas here shown, the nosing element or member is for the reception of securing screws 3 for securing the nosing to the forward edge portions of stair treads t as indicated. The nosing element may be rolled or cast or extruded of suitable material such as yellow oi white brass, adapted to eflectively protect the stair coveringindicated at 5 and of the, character heretofore referred to. The upper portion of the nosing flange 1 extends or projects upwardlyabove the securing flange 2 a distance substantially corresponding to the depth or thickness of the covering 5 to be applied to the stair tread and the lower portion of the nosing flange 1 may desirably and as shown, project downwardly from the securing flange a distance corresponding to the thickness of the stair tread 4, thereby to present a unitary and attractive appearance.

The securing flange 2 is integrally formed toextend longitudinally of the nosing and in accordance with the present invention is of improved cross-sectional contour to fa- ,cilitate and" effect a substantial economy in be in a horizontal plane to have a firm bearing' formed with a 'curved nosing or facing flange L rest upon the upper marginal edge surface of the stair tread and the tapered form is produced by the progressive and rearward incli-' nation of the upper surface to substantially 5 a point or sharpened edge at the rearward l0 flange 2 and extending forwardly to the nosing. The structure, accordingly, allows of installing the nosing without cutting of the tread or cutting or building up of the cover material to be used therewith and the rear- Ward taper of the securing flange to a relaexcessive wear which would occur were the shoulder tively t in sharpened edge, substantially eliminates the formation of a shoulder at its rearward edge. The elimination of the shoulder, as heretofore described, overcomes the present and likewise, danger of tripping and the improved tapered securing flange further provides a desirable slight inclination to the tread surface at its forward edge conducive to safety in the use of the stairs.

It will be understood that the improvements are concerned more particularly with the special shape of the securing flange, which 3 extends under the floor covering, and the upstandin portion of the nosing flange which abuts tli e edge of the floor covering, as distinguished from the depending portion of the nosing flange which faces the edge of a stair tread in usual manner.

It will also be understood that the relatively thin and sharp edge of the securing flange is not necessarily a cutting edge, but such an ed e as may be made by extruding the metal t rough a die in accordance with well known practice.

Having described my invention, I claim like comprising a nosing flange and' a securing flange extendin rearwardly therefrom, said securing flange having its underside surface in a horizontal plane and its upper surface inclined rearwardly to a rearward edge of minimumthickness whereby said upper 1., A nosing member for stair treads and the surface of the stair tread.
